4 Claims.

My invention relates generally to a drain plug for a wash basin or the like, and particularly to a plug of this character which is equipped with a duplex, reversible strainer, and an important object of the invention is to provide an arrangement of this character in which the strainer element is readily removable for cleaning without disturbing the spud connected to the basin and without disturbing the trap of the basin.

Another important object of the basin is to provide a basin plug of the character indicated above which will catch all hair, lint, grease, dirt, and other objects before the same passes into the basin trap, after the water leaves the basin through the plug or spud.

Another important object of the invention is to provide a lavatory basin spud which will fit new and old lavatory basins simply by removing the old plug and installing the new one, the plug of the present invention having a standard threaded connection on the bottom which fits all the connections of the trap, so that it is unnecessary to install a new trap for connection to the lavatory basin.

Other important objects of my invention will be apparent from a reading of the following description in connection with the drawing, wherein for purposes of illustration I have shown a preferred embodiment of the invention.

In the drawing:--

Figure 1 is a general transverse vertical sectional view taken through the embodiment.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a horizontal sectional view taken through Figure 1 approximately on the line 33 and looking downwardly in the direction of the arrows.

Figure 4 is a side elevational view of the em- 40 bodiment.

Figure 5 is a side elevational view of the duplex strainer per se.

Referring in detail to the drawing, the numeral 5 generally designates the exterior cylindrical 45 shell which has on its upper end the angulated flange 6 arranged to seat in the plug opening in the basin or the like, and the side openings 1 which are circumferentially spaced in the cylinder 5 for admitting the overflow from the basin into the trap of the basin.

Suitably secured to the lower end of the shell 5 and extending telescopically therein is the threaded connection 8 which is exteriorly 55 threaded as indicated by the numeral 9, the spud 8 being of standard thread size for connection to the connections of trap of the basin.

Resting on the upper edge of the spud 8 is the duplex strainer which is generally designated l0 and which comprises the generally cylindrical body ll having the circumferentially spaced side openings l2 registrable with the side openings 1 of the outer shell 5 as indicated in Figures 1 and 4. The cylinder I l includes the intersecting cross members I3 and l 4 at the upper end thereof from the point of intersection of which rises the handle IS in the form of a ball. Across and within the lower end of the cylinder II is the relatively fine mesh screen [6. The lower end of the cylinder rests on the upper end of the spud 8. The cruciform top formed by the intersecting cross members l3 and i4 is slightly downset as indicated in Figure 1 whereby to define an annular ridge I! which is adapted to rest on the upper end of the spud 8 when the strainer is used in a reversed position. It will be observed that the strainer It is normally positioned sufiiciently below the upper end of the shell 5 to admit the use of a plug or stopper in the upper end of the shell 5 in the usual manner. This makes it possible to use a plug in the upper end of the shell 5 while the strainer Ill is entirely removed, as for cleaning, without letting any of the water from the basin into the trap while the strainer is removed.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials, and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claims.

What is claimed is:-

1. A basin spud comprising an outer shell for mounting in the drain opening of the basin and arranged for connection to the trap of the basin, a shoulder within the lower end of the shell, side drain openings in the walls of said shell above said shoulder, and strainer means resting on said shoulder within said shell, said strainer being reversible and removable having vertically spaced therein a fine mesh strainer and cross guards, said strainer being tubular in form and formed with side drain openings registrable with I its upper end formed to receive a drain plug, an interior shoulder adjacent the lower end of said tube, a basket supportably resting on said shoulder, said basket having a perforated top located sufiiciently below the upper end of said tube to permit full seating of the drain plug in the upper end of the tube, said cage and said tube having registering side drain openings.

3. A drain fixture for a wash basin or the like, said fixture comprising a tube to traverse the drain opening in the basin, said tube having its upper end formed to receive a drain plug, an interior shoulder adjacent the lower end of said tube, a basket supportably resting on said shoulder, said basket having a perforated top located sufiiciently below the upper end of said tube to permit full seating of the drain plug in the upper end of the tube, said cage and said tube having registering side drain openings, said perforated top of the cage including a handle enabling lifting out the cage.

4. A drain fixture for a wash basin including a drain opening, said fixture comprising a tubular shell disposed in and below said drain opening, a spud telescoped in the lower end of said shell and defining a shoulder in said shell, a tubular cage having a perforated top and a screen bottom, said cage supportably resting on said shoulder within said shell, the top of said cage being sufficiently depressed below the top of said tubular shell to permit the top of said shell to receive said drain plug, said cage and said shell being formed in their sides with registering drain openmgs.
